Application led ,September production of apadlock olthe above char-2` y acter having lockingmeans adaptedto inter-y lock with the legs ol1 theshackle and adaptnism," the key plugof said mechanism be. ing prevented `from forward withdrawal through the padlockby said locking` means.

A further object of the inyention isthe production of a padlock having` a shackle oney leg of which may be entirely withdrawn from the padlock while the other leglof the shackle may normally not be withdrawn and means permitting both legs to be withdrawn when desired whereby a new p shackle `may be substituted. M, f..

A 'further object 'of theiinvention is the production of a padlock provided with lock ing means actuated bythe key plug' oit apin` tumbler mechanism. y ,y

`A still further. object of the invention is the yproduction of a padlock `provided with locking mcansadapted tointerlock with both sides of bothlcgs oft` the shackle.

` AStill other and urt-herobjects and 'advantagesof the invention are `the provision of a padlock in whichthe casingr thereof acts as a stop to limit the movement ol* the shackle locking' means,` the provision oi'if vmeans in the padlock.actingto retain the shackle locking` means in locked position and to retain the keyplug in proper position foi.' .insertion of the key, andthe provision of padlock having a novel construction'permitting the interior mechanism thereof to be slipped as a unit and in' operative position iuto the casing. i j i The invention consists inthe :novel parts and combinzrtions thereofhereinafter more particularly describcdand then specilied .in
